Hamas is NOT an insurgency. It is the ruling power of Gaza that had complete control of a geographic area, a population, all institutions, and a vast military (40,000 fighters, 15-20k rockets, 400 miles of military tunnels up to 200ft under ground, and a massive array/supply of small arms, mortars, crew served weapons, anti-tank missiles, anti-aircraft guns, mines, improvised explosive devices, and other weapons supplies arrayed in a 15 year prepared defensive posture) with the stated and written objective to destroy Israel and all jews of the world. Israel is NOT conducting a counterinsurgency or counterterrorism campaign. Israel is conducting a war to remove a regime (happens to also be a terrorist organization) from power and dismantle its military. To say Israel cannot "destroy Hamas” through military force, that it increases Hamas's “support” or “you can’t destroy an idea or terrorism like this” is a fallacy. Israel’s war on Hamas step one is to remove them from power and dismantle their military capability. Dismantle. Defang. After step one, many elements of the clear, build, hold post-conflict phase of a war to include reconciliation and de-radicilzation will be a focus. The counterinsurgency or counterterrorism line of thinking applied to even unconventional war where the goal is to remove a power/regime and destroy/dismantle/defeat their military is equal to saying you can’t remove Hitler from power or destroy the Nazi military in Germany because of concern for further hardening the beliefs and sentiment of the portion of the German population who supported the Nazis.
